## What is CVE-2018-0359?

CVE-2018-0359 is a medium-severity authentication bypass vulnerability in Cisco Meeting Server unknown, published on 21 Jun 2018. It can only be exploited from the same machine or local network, with no action from the victim.

### Official description

A vulnerability in the session identification management functionality of the web-based management interface for Cisco Meeting Server could allow an unauthenticated, local attacker to hijack a valid user session identifier, aka Session Fixation. The vulnerability exists because the affected application does not assign a new session identifier to a user session when a user authenticates to the application. An attacker could exploit this vulnerability by using a hijacked session identifier to connect to the application through the web-based management interface. A successful exploit could allow the attacker to hijack an authenticated user's browser session. Cisco Bug IDs: CSCvi23787.

Weakness: CWE-384 (Session Fixation)

What it is: CVE-2018-0359 is a medium-severity authentication bypass vulnerability in Cisco Meeting Server unknown, published on 21 Jun 2018. It can only be exploited from the same machine or local network, with no action from the victim.
Exploitation: There is no known exploitation of CVE-2018-0359 in the wild and no public exploit code.

Affected product: Cisco Meeting Server unknown. No package-level version data is available, so check the vendor advisory linked from the reference page.

Task:
1. Search the dependency manifests and lockfiles (for example package.json, package-lock.json, requirements.txt, poetry.lock, uv.lock, pom.xml, build.gradle, go.mod, Cargo.lock, Gemfile.lock) and any Dockerfiles for the affected packages, including transitive dependencies.
2. If an affected version is in use, upgrade it to the fixed version for its release line with the project's package manager, so the lockfile is regenerated. Prefer the smallest upgrade that fixes it.
3. If there is no fix, or the upgrade would break the build, do not guess: explain the risk and the safest workaround instead.
4. Run the tests and summarise what changed and why.
5. If nothing in the project is affected, say so and change nothing.
